Baby Development
The brain is highly active, sleep cycles are becoming more organised, and the lungs continue maturing for life outside the womb. The baby's kicks and stretches may feel stronger because muscle tone is improving too.
Baby Size
A playful size comparison for this week is cabbage. That cabbage-sized baby is now sturdy enough to make movement a real presence in your day.
Mother's Body Changes
As the bump grows, you may notice more pelvic heaviness, more obvious posture changes, and more effort required for ordinary movement. Swelling and heartburn can also begin taking up more space in daily comfort.
Common Symptoms
Week 27 can bring active movement, back pain, heartburn, leg cramps, mild swelling, and interrupted sleep. Braxton Hicks may be easier to recognise now, especially after dehydration or overdoing things.
Nutrition Tips
Think ahead to third-trimester stamina by keeping iron, protein, fibre, and hydration consistent rather than waiting until you feel depleted. If reflux is strong, smaller meals and an earlier dinner can genuinely help.
Exercise & Movement
Comfort-led movement is still a smart goal: walking, stretching, swimming, and prenatal mobility work often fit beautifully here. Recover well after activity, because the body notices overexertion more quickly now.
Emotional Wellbeing
Closing the second trimester can feel encouraging, but it may also make the remaining weeks feel suddenly real. Big milestones often carry mixed emotions.
Partner Support
A partner can help by treating the transition into the third trimester as meaningful, not just routine. Sometimes being seen and celebrated for how much your body has done already is powerful.
Warning Signs
Urgent warning signs this week include heavy bleeding, severe abdominal pain, fever, fainting, leaking fluid, or a severe headache with vision changes. Call your doctor for regular painful tightenings, leaking fluid, bleeding, severe swelling, or headaches that do not ease with rest.
Frequently Asked Questions
Yes, it is commonly treated as the tail end of the second trimester, with the third trimester beginning around week 28.
